<br/><br/> PUVA therapy has long been considered a standard line of treatment for vitiligo that can stimulate melanogenesis . The response to PUVA therapy has always been deficient in some anatomical sites including hands, feet and periorificial areas . Treatment of these areas has always been a therapeutic challenge . To clarify causes of resistance at those sites by studying the expression of stem cell factor on keratinocytes and c - kit receptor on melanocytes in both resistant and responding lesions of vitiligo before and after photochemotherapy
